They are -12 offset and 4.5 backspace 17X9 rim with 265 70 17 on my stock 99 4runner limited 4x4?
17x9 ultra 164 rims with
265/70/17
Uhh, It looks like they should fit no problem... why would you get the same size tire with a bigger rim? Im no tire expert, but it appears you are going to have the same tire height with a bigger rim... so all you get is a bigger hole in the center of the same size tire...
Am I right?!! I may not be... but maybe the offset is different...
No, your wrong. That size is equivalent to a 265/75/16.
